Emergence of resistance by bacterial and fungal stains towards existing antimicrobial agents is one of the major problem as well as motivation to synthesize a new class of antimicrobial agents possessing potent activity compared to commonly used therapy. Coumarin is the heterocyclic compound formed from benzene and pyrone ring containing oxygen and its derivatives are of wide awareness because ...

actinomycetes were isolated from marine sediment samples collected from the east coast of chennai, tamil nadu, india. well diffusion and agar plug methods were used for the evaluation of antibiotic production by these isolates against drug resistant methicillin- resistant staphylococcus aureus (mrsa) and vancomycin resistant enterococci (vre). the potential isolate vitbrk2 was mass cultured for...

a long-term study was conducted between 1985 and 2003 on rehabilitation trials at sishen ironore mine, south africa, to identify grass species that would survive in the artificial growth medium appliedto the sites, and to determine the most suitable medium for sustainable vegetation growth. vegetationestablishment was tested at slopes of 18° and 34° and with five different cover materials. afte...

Intriguingly, activated complement and anti-microbial peptides share certain functionalities; lytic, phagocytic, and chemo-attractant activities and each may, in addition, exert cell instructive roles. Each has been shown to have distinct LPS detoxifying activity and may play a role in the development of endotoxin tolerance. In search of the origin of complement, a functional homolog of complem...

silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. a simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles.  the present study aimed at the comparative study of silver nanopartic...

We explore the anti-microbial activity of urine specimens after the ingestion of a commercial cranberry preparation. Twenty subjects without urinary infection, off antibiotics and all supplements or vitamins were recruited. The study was conducted in two phases: in phase 1, subjects collected the first morning urine prior to ingesting 900 mg of cranberry and then at 2, 4 and 6 h. In phase 2, su...
